Mercury levels in a 21-year-old black crowned night heron were measured. Concentrations were: breast muscle (0.9 ppm), liver (3.1 ppm), brain (0.5ppm), and primary wing feathers (17.9 ppm). These levels were not substantially different from those found in much younger birds. These data imply that either the kind had been feeding in an area with low levels of mercury contaminations or that the maximum retainable mercury in black-crowned night herons is specific to an individual. 4 references.
